Abstract

The Ca and P containing TiO ₂ coating was fabricated on NiTi alloy by PEO treatment in an organic electrolyte containing TiO ₂ collosol and Ca-Gp. The surfaces of the coating exhibit a typical PEO porous and rough structure. The XPS analysis indicates that the coatings are mainly composed of Ti, O, C, Ca, P and a little amount of Ni. The concentration of Ni is greatly reduced compared to that of the NiTi substrate. The XRD analysis indicates that the Ca and P elements existing in the PEO coating are mainly in the form of Ca ₂ P ₄ O ₁₂ . The curves of potentiodynamic porlarization suggest that the corrosion resistance of the NiTi alloy is significantly improved by the TiO ₂ coating formed on its surface by PEO treatment. The thickness, bonding strength and the corrosion resistance of the PEO coating are obviously affected by adding of Ca-Gp in the electrolyte. The bioactivity of PEO coating is significantly improved due to the incorporation of Ca and P composition, and so exhibits an excellent apatite-forming ability in SBF solution.
